Description:
------------
When aliasing an importing traitmethod without explicitely declaring the trait's name, ReflectionClass::getTraitAliases() renders the traitname as '(null)'.

The method should render the correct traitname, as if the aliasing had been done using the full qualifier.

(Actually, my PHP-version is 5.4.7, not 5.4.7RC1)

Test script:
---------------
trait MyTrait
{
    public function run() {}
}

class MyClass
{
    use MyTrait {
        run as execute;
    }
}

var_export((new \ReflectionClass('MyClass'))->getTraitAliases());

Expected result:
----------------
array (
  'execute' => 'MyTrait::run',
)

Actual result:
--------------
array (
  'execute' => '(null)::run',
)

A quick fix is:

but seems an existsing test take it as a expect output, see:

will verify it later.
